SphereReflectionCaptures cause incorrect dynamic lighting results on mobile

Hi, there :

I bought Ancient Environment in Marketpalce. It’s an amazing product. In the Showcase.umap, I found that if I set all SphereReflectionCaptures’ “Actor Hidden In Game” to true, the mobile preview will not render the specular lighting of the Water Material. Unless I set the Actor SpereReflectionCapture1’s “Actor Hidden In Game” to false.

Best regards.

That’s because reflection captures capture the reflection, and when you disable them you need a movable skylight in order to have reflections on translucent materials(even for opaque materials, since without reflection captures you use SSR and that has its limitations.
